大脑中动脉的急性闭塞经常发生和特别危险,它使神经外科医生极为关注的是能否进行外科治疗。产生大脑中动脉闭塞的常见原因是风湿和动脉硬化。心血管和脑血管外科手术范围的扩大,广泛的应用颅内血管造影,及最近血管内手术的发展等对大脑中动脉的闭塞的增加起着一定的作用。尤应强调指出的是、神经外科医师对这个问题的关注还因为脑血管显微外科手术的发展。脑血管显微外科手术在许多情况下可以清除脑血管的急性闭塞并恢 Acute occlusion of the middle cerebral artery is a frequent and particularly dangerous condition that makes neurosurgeons extremely concerned with the possibility of surgical treatment. Common causes of middle cerebral artery occlusion are rheumatism and atherosclerosis. The expanding range of cardiovascular and cerebrovascular surgery, extensive use of intracranial angiography, and recent advances in endovascular procedures play a role in the increase of occlusion of the middle cerebral artery. In particular, it is emphasized that neurosurgeons also pay attention to this issue because of the development of cerebrovascular microsurgery. Cerebral vascular microsurgery in many cases can clear the acute occlusion of cerebral blood vessels and recovery
